I just installed retropie and am running into a few issues. Whenever I try to run any N64 game, I have heard that only certain games run ok on the pi, so I tried to run Super Mario 64 and a couple others and got this error.
/opt/retropie/supplementary/runcommand/runcommand.sh line23: mupen64plus command not found.
I am also having difficulty trying to get star fox working on the super nintendo. I try to start it up and am greeted by a black screen.
